From the WUWT post "Weather Channel Founder John Coleman: There is no significant man-made global warming at this time," a comment and link demonstrates that all of the alleged global warming including average, minimum, and maximum surface temperature anomalies since 1940 is due to the artificial "processing" of data, and not found in the raw data:
above comments from the WUWT post:
John Coleman, the founder of Weather Channel, has written an open letter, in which he claims the theory of anthropogenic climate change is no longer scientifically credible. So far The Express, a major British newspaper, and the American news service WND, have provided favorable coverage of the letter. The Express article has also been linked to by the Drudge Report, giving it wide exposure. The full text of the letter is as follows:
_______________________________________
"Taken together a couple of things are clear, for most of the world there was no trend in minimum temperature when CO2 increases became significant, and then in the early 70’s most of the planet experienced a significant drop in minimum temperature, followed by a slow recovery."
Here’s proof, this is only surface measurements.
The warming we’ve seen in temp series is due to the actual processing of the data.
- I can confirm that Australian maximum temperatures show no secular trend over the 20th century.
- I haven’t seen this before. Can you point me to a url or paper explaining the data? Thanks
- OldDude commentedI haven’t seen this before. Can you point me to a url or paper explaining the data? ThanksFollow the URL in my name for code and data, I have more of a description hereIt has evolved over time, but for the most part it’s been tightening up the data selection to have better control over whether partial year stations are included or not.
Micro: Surface temperature of what (US/World?). Also link so I can post. Thanks.
- Thom commentedMicro: Surface temperature of what (US/World?). Also link so I can post. Thanks.95 million surface station records, from around the globe, from the NCDC Global Summary of Days dataset.
This graph is fresh from this morning where I added average temps to min and max. For this, just right click and copy url link, the data (previous version without average temps) at the url in my name, and you can follow the science 2.0 link for more wordy stuff. - milodonharlani commentedBefore or after adjustments?NCDC says here ftp://ftp.ncdc.noaa.gov/pub/data/gsod/readme.txt they do some QAAs for quality control (QC), the input data undergo extensive
automated QC to correctly ‘decode’ as much of the synoptic data as
possible, and to eliminate many of the random errors found in the
original data. Then, these data are QC’ed further as the summary of
day data are derived. However, we expect that a very small % of the
errors will remain in the summary of day data.I have found some bad temps that I filter out (above and below 199F/-199F, so I presume they are actually bad). I do no adjustments.

Weather Channel Founder John Coleman: There is no significant man-made global warming at this time

Dear UCLA Hammer Forum officials,
There is no significant man-made global warming at this time, there has been none in the past and there is no reason to fear any in the future. Efforts to prove the theory that carbon dioxide is a significant “greenhouse” gas and pollutant causing significant warming or weather effects have failed. There has been no warming over 18 years. William Happer, Ph.D., Princeton University, Richard Lindzen, Ph.D., Massachusetts Institute of Technology, Willie Soon, Ph.D., Harvard Smithsonian Observatory, John Christy, Ph.D., University of Alabama and 9,000 other Ph.D. scientists all agree with my opening two sentences.
